The edges of the cabinet's baffle should be slanted or rounded.
The recess depth for the tweeter should be 3 mm or 6 mm, in which case
2 layers of sealing tape or 3 mm cardboard should be used.
The cabinet should be damped with half a pack of polyester fleece, to be placed
in the centre.
If a valve amp is being used we recommend to adjust the impedance by installing
a serial resonant circuit with the following components:
- 10 Ohm MOX 10 resistor (brown-black-black),
- 0,68 mH air-core coil, 0,7 mm
- 22 uF electrolytic capacitor, smooth
All components need to be connected in series, the two ends will be connected
to the loudspeaker terminals.
